- Request POST_NOTIFICATIONS permission at runtime in MainActivity (primary fix
for notifications never appearing on Android 13+ phones including Android 16)
- Register all 4 notification channels eagerly in SyncFlowApp.onCreate() instead
of lazily inside workers
- Add FOREGROUND_SERVICE_SHORT_SERVICE permission + shortService foreground type
for Android 16 foreground service compatibility
- Add global activity Log tab (new tab 2 in main nav) showing all sync events
across all pairs, grouped by date with pair name, event icon, and file detail
- Fix FileWatchService ON_CHANGE detection: ContentObserver on SAF tree URIs only
fires for SAF-API writes, not raw filesystem writes. Now resolves primary:/*
tree URIs to /storage/emulated/0/* and uses FileObserver for reliable detection
- Bump version to 1.0.21 (build 22)

Sync change detection:
- DbConverters was using epochSecond but comparisons used epochMilli —
every file appeared modified on every scan, causing full re-sync each time
- DB migration 2→3 clears sync_file_states (all stored timestamps wrong)
- First sync after upgrade re-learns state; subsequent syncs skip unchanged files
Biometric:
- Move prompt trigger from LaunchedEffect to onResume() — guarantees
the activity is in RESUMED state when authenticate() is called
- Add bestAuthenticators(): tries BIOMETRIC_STRONG|DEVICE_CREDENTIAL first,
falls back to BIOMETRIC_WEAK|DEVICE_CREDENTIAL for side-sensor phones
- canAuthenticate() now accepts either strong or weak+credential
- onAuthenticationError always shows Unlock button (no infinite retry loop)
- isLocked/showRetry are Activity-level state, no need for Compose remember

Biometric:
- Handle onAuthenticationError with auto-retry (except user cancel)
- Show lock screen with proper UI and an Unlock button as fallback
- Add subtitle clarifying fingerprint/PIN options
Sync engine:
- Fix data race: async coroutines now return FileOutcome instead of
mutating shared vars/list concurrently (was causing file states to
not be saved, so every sync re-transferred all files)
- Fix remoteChanged: use || instead of && so either etag or
modifiedAt change is enough to detect a remote modification
